Air quality — Environmental meteorology — Part 4: Ground-based remote sensing of meteorological para...
This Standard describes the determination of height-resolved profiles of atmospheric backscattering by means of active optical sounding. The measurements allow the following properties of the atmosphere up to several kilometres above ground to be derived:
• Cloud bases
• Upper boundaries of optically thin clouds
• Upper and lower boundaries and internal structures of particle layers:
– The height…
Vegetable fats and oils — Isomeric diacylglycerols — Determination of the content and relative amoun...
This International Standard specifies the determination of the degree of isomerization of diacylglycerols in vegetable fats and oils. 1,2-diacylglycerols are transformed to the more stable 1,3-isomers during storage or due to acidic catalyzed reaction.
The mass fraction of 1,2-diacylglycerols can be used as a quality criterion for vegetable fats and oils. The absolute content of diacylglycerol…
Surface active agents — Soaps — Determination of chloride content by potentiometric method
This document specifies a potentiometric method for the determination of the chloride content of soaps, containing or not containing other surface active agents, and also of compounded products.

Enterprise-control system integration — Part 2: Objects and attributes for enterprise-control system...
This part of IEC 62264 specifies generic interface content exchanged between manufacturing control functions and other enterprise functions. The interface considered is between Level 3 manufacturing systems and Level 4 business systems in the hierarchical model defined in IEC 62264-1. The goal is to reduce the risk, cost, and errors associated with implementing the interface.
Since this standard…
Plastics — Aromatic isocyanates for use in the production of polyurethanes — Determination of total ...
ISO 26603:2017 specifies the determination of the total chlorine content of aromatic isocyanates used in the preparation of polyurethanes. The difference between the total chlorine content and the hydrolyzable chlorine content (see ISO 15028) is a measure of the process solvents left in the product. Both test methods are applicable to a variety of organic compounds, including aliphatic…
Road vehicles — On-board diagnostic communication — Part 3: Zero emissions vehicle propulsion system...
ISO/SAE 1979-3 is intended to satisfy the data reporting requirements of regulations in the United States and Europe, and any other market that may adopt similar requirements in the future.
This document specifies diagnostic services required to be supported by motor vehicles and external test equipment for diagnostic purposes which pertain to Zero Emission Vehicle (ZEV) propulsion related data…
Cryogenic vessels — Pressure-relief accessories for cryogenic service — Part 3: Sizing and capacity ...
ISO 21013-3:2016 provides separate calculation methods for determining the required mass flow to be relieved for each of the following specified conditions:
- vacuum-insulated vessels with insulation system (outer jacket + insulating material) intact under normal vacuum, outer jacket at ambient temperature, inner vessel at temperature of the contents at the specified relieving pressure;
- vacuum-…
